TECHNICAL FIELD OF THE INVENTION
The present invention relates to an entry / exit management system that performs personal identification using a card and controls a door.
[0002]
[Prior art]
FIG. 6 is a configuration diagram of a conventional entry / exit management system of this type. 6, 1 is a passerby, 2 is a card held by the passer, 3 is a card reader, 4 is a central processing unit in the card reader 3, 5 is a card personal identification number in the card 2, and 6 is a card in the card 2. A card reading unit for reading the card personal identification number 5; a passability database 7 for judging whether the card personal identification number 5 is passable; a human sensor 8 for detecting the passerby 1 and increasing the output as the person approaches; Is a sensitivity setting set by a volume or the like, 10 is a comparator for comparing the human sensor 8 with the sensitivity setting 9, 11 is a door control unit in the card reader 3, and 12 is a door controlled by the door control unit 11.
[0003]
FIG. 7 is an operation flowchart of the system of FIG. When the passerby 1 approaches the card reader 3, the output of the human sensor 8 gradually increases, and when the sensitivity exceeds the sensitivity setting 9, the comparator 10 outputs a signal to that effect to the central processing unit 4 (step S1). . The central processing unit 4 enables the card reading unit 6 (step S2) so that the card personal identification number 3 in the card 2 can be read. When the card reading unit 6 reads the card personal identification number 5 in the card 2 within a predetermined time (for example, 5 seconds) (step S3), the central processing unit 4 checks the card personal identification number 5 against the passability database 7. (Step S4) Then, the card reading section 6 is invalidated (Step S5). If the collation result indicates that the vehicle is passable, the central processing unit 4 temporarily unlocks the door 12 via the door control unit 11 (step S4), and then returns to the initial state. On the other hand, if the collation result indicates no traffic, the central processing unit 4 returns to the initial state without temporarily unlocking (step S4).
[0004]
If the card reading unit 6 cannot read the card personal identification number 5 in the card 2 within a predetermined time, the central processing unit 4 invalidates the card reading unit 6 and returns to the initial state (step S3).
[0005]
The sensitivity setting 9 is set according to the surrounding situation when the card reader is installed. Normally, when installed in a place where there are many traffics, the sensitivity setting 9 is set higher, and the comparator 10 does not output unless the passerby 1 approaches the vicinity of the card reader 3. Conversely, when the device is installed in a place where traffic is small, the sensitivity setting 9 is set to a lower value so that the comparator 10 does not output even if the passerby 1 is far from the card reader 3.
[0006]

BEST MODE FOR CARRYING OUT THE INVENTION
Embodiment 1 FIG.
FIG. 1 is a configuration diagram of an entry / exit management system according to an embodiment of the present invention, in which the same or corresponding parts as those in the related art are denoted by the same reference numerals (the same applies to the following embodiments).
[0012]
In FIG. 1, 1 is a passerby, 2 is a card held by the passer, 3 is a card reader, 4 is a central processing unit in the card reader 3, 5 is a card personal identification number in the card 2, and 6 is a card in the card 2. A card reading unit for reading the card personal identification number 5; a passability database 7 for judging whether the card personal identification number 5 is passable; a human sensor 8 for detecting the passerby 1 and increasing the output as the person approaches; Is a sensitivity setting set in the central processing unit 4, 10 is a comparator for comparing the human sensor 8 with the sensitivity setting 10 (8, 9, and 10 are human sensor units), and 13 is a result of the comparator 10. A sensitivity adjustment database accumulated through the central processing unit 4, 11 is a door control unit in the card reader 3, and 12 is a door controlled by the door control unit 11.
[0013]
FIG. 2 is an operation flowchart of the system of FIG. When the passerby 1 approaches the card reader 3, the output of the human sensor 8 gradually increases, and when the sensitivity exceeds the sensitivity setting 9, the comparator 10 outputs a signal to that effect to the central processing unit 4 (step S1). . The central processing unit 4 enables the card reading unit 6 so that the card personal identification number 5 in the card 2 can be read (step S2). When the card reading unit 6 reads the card personal identification number 5 in the card 2 within a predetermined time (for example, 5 seconds) after the output of the comparator 10 (step S3), the central processing unit 4 sends the sensitivity adjustment database 13 Is recorded as a normal operation (step S6), the central processing unit 4 checks the card personal identification number 5 against the passability database 7 (step S4), and thereafter invalidates the card reading unit 6 (step S5). Here, the central processing unit 4 temporarily unlocks the door 12 via the door control unit 11 when the collation result indicates that the vehicle is passable. Not performed (step S4).
[0014]
If the card reading unit 6 cannot read the card personal identification number 5 in the card 2 within a predetermined time after the output of the comparator 10, the central processing unit 4 erroneously senses the sensitivity adjustment database 13 (door control). The central processing unit 4 disables the card reading unit 6 (step S5) and returns to the initial state.
[0015]
The sensitivity setting 9 is determined based on the sensitivity adjustment database 13. If the ratio of the number of “normal operations” and the number of “false senses” during a predetermined period (eg, one week) is higher than a predetermined value (eg, the ratio of “false senses” is 80% of the whole), central processing is performed. The device 4 sets the sensitivity setting 9 higher, so that the comparator 10 does not output until the passerby 1 is closer to the card reader 3. Conversely, when the ratio is lower than a predetermined value (for example, the ratio of “false sense” is 80% of the whole), the central processing unit 4 sets the sensitivity setting 9 to a lower value, and the passerby 1 moves far from the card reader 3. However, the comparator 10 outputs (steps S8 and S9). Note that the criterion for the sensitivity adjustment may be a desired value depending on the installation environment of the card reader, especially the sensor.
[0016]
Embodiment 2 FIG.
FIG. 3 is a configuration diagram of an entry / exit management system according to another embodiment of the present invention, and the same or corresponding parts as those in the above embodiment are denoted by the same reference numerals. FIG. 3 shows the system of the second and third embodiments in common. In the second embodiment, a liquid crystal display unit 14 for displaying operation guidance and a state of the card reader 3 and the liquid crystal display unit 14 are displayed. A liquid crystal display backlight 15 to be provided is further provided. Then, as will be described later, the backlight 15 of the liquid crystal display unit is turned on in response to the detection of a pedestrian. In this embodiment, the card reading section 6 is always in the valid state.
[0017]
FIG. 4 is an operation flowchart in this embodiment. When the passerby 1 approaches the card reader 3, the output of the human sensor 8 gradually increases, and when the sensitivity exceeds the sensitivity setting 9, the comparator 10 outputs a signal to the central processing unit 4 (step S1). The central processing unit 4 turns on the liquid crystal display unit backlight 15 (step S12). When the card reading unit 6 reads the card personal identification number 5 in the card 2 within a predetermined time (for example, 5 seconds) after the output of the comparator 10 (step S3), the central processing unit 4 sends the sensitivity adjustment database 13 Is recorded as a normal operation (step S6), the central processing unit 4 checks the card personal identification number 5 against the passability database 7 (step S4), and then turns off the liquid crystal display unit backlight 15 (step S13). ). Here, the central processing unit 4 temporarily unlocks the door 12 via the door control unit 11 when the collation result indicates that the vehicle is passable. Not performed (step S4).
[0018]
If the card reading unit 6 cannot read the card personal identification number 5 in the card 2 within a predetermined time after the output of the comparator 10, the central processing unit 4 erroneously senses the sensitivity adjustment database 13 (door control). The central processing unit 4 turns off the backlight 15 of the liquid crystal display (step S13) and returns to the initial state.
[0019]
On the other hand, when the card reading unit 6 reads the card personal identification number 5 in the card 2 in a state where the comparator 10 has not detected the output to the central processing unit 4 (step S10), the central processing unit 4 returns to the back of the liquid crystal display unit. The light 15 is turned on (step S12a), and recorded in the sensitivity adjustment database 13 as undetected (the reading of the personal identification number by the reading unit without the detection of a pedestrian) (step S11). Do the lock.
[0020]
The sensitivity setting 9 is determined based on the sensitivity adjustment database 13. If the ratio of the number of “normal operations” and the number of “false senses” during a predetermined period (eg, one week) is higher than a predetermined value (eg, the ratio of “false senses” is 80% of the whole), central processing is performed. The device 4 sets the sensitivity setting 9 higher, so that the comparator 10 does not output until the passerby 1 is closer to the card reader 3. Conversely, when the ratio is lower than a predetermined value (for example, the ratio of “false sense” is 80% of the whole), the central processing unit 4 sets the sensitivity setting 9 to a lower value, and the passerby 1 moves far from the card reader 3. However, the comparator 10 outputs the signal. However, if the ratio of the number of times of “normal operation” and the number of times of “undetected” during a predetermined period (for example, one week) is lower than a predetermined value (for example, the ratio of “undetected” is 80% of the whole), Regardless of the sensitivity setting, the central processing unit 4 sets the sensitivity setting 9 to a lower value so that the comparator 10 outputs even if the passerby 1 is far from the card reader 3 (steps S8 and S9a). Note that the criterion for the sensitivity adjustment may be a desired value depending on the installation environment of the card reader, especially the sensor.
[0021]
Embodiment 3 FIG.
FIG. 5 is an operation flowchart of an entry / exit management system according to still another embodiment of the present invention. The system configuration further includes a touch panel switch 16 attached to the liquid crystal display unit 14 and operated by the passerby 1 in FIG. In this embodiment, the card reading unit 6 and the liquid crystal display unit backlight 15 are used to output at least the output of the comparator 10 (perception by the human sensor units 8 to 10) and the contact with the touch panel switch 16 by the detection of a pedestrian. It is enabled or turned on in conjunction with one of them.
[0022]
To explain according to the operation flowchart of FIG. 5, when the passerby 1 approaches the card reader 3, the output of the human sensor 8 gradually increases, and when the sensitivity exceeds the sensitivity setting 9, the comparator 10 informs the central processing unit 4 of that. A signal is output (step S1). The central processing unit 4 turns on the liquid crystal display unit backlight (step S12). Further, the central processing unit 4 enables the card reading unit 6 (step S2). When the card reading unit 6 reads the card personal identification number 5 in the card 2 within a predetermined time (for example, 5 seconds) after the output of the comparator 10 (step S3), the central processing unit 4 sends the sensitivity adjustment database 13 Is recorded as a normal operation (step S6), the central processing unit 4 checks the card personal identification number 5 against the passability database 7 (step S4), and then turns off the liquid crystal display backlight 15 (step S13). Then, the card reading unit 6 is invalidated (step S5). Here, when the collation result indicates that the vehicle is passable, the central processing unit 4 temporarily unlocks the door 12 via the door control unit 11, and conversely, when the collation result indicates that the vehicle is not passable, the unlocking is performed. Not performed (step S4).
[0023]
If the card reading unit 6 cannot read the card personal identification number 5 in the card 2 within a predetermined time after the output of the comparator 10, the central processing unit 4 records it in the sensitivity adjustment database 13 as a false sense. (Step S7), the central processing unit 4 turns off the liquid crystal display unit backlight 15 (Step S13), disables the card reading unit 6 (Step S5), and returns to the initial state.
[0024]
On the other hand, when the pedestrian 1 touches (touches) the touch panel switch 16 without the comparator 10 outputting to the central processing unit 4 and not detecting it (step S14), the central processing unit 4 turns on the liquid crystal display unit backlight 15. (Step S15), and activates the card reading section 6 (step S16). When the card reading unit 6 reads the card personal identification number 5 in the card 2 (step S10), the central processing unit 4 records it as undetected in the sensitivity adjustment database 13 (step S11), and then checks in step S4. Release the lock. Note that if it is determined that a passer-by has touched the touch panel switch 16 and the touch panel switch 16 has not been detected, step S10 is unnecessary.
[0025]
Further, the sensitivity adjustment processing in steps S8 and S9a is the same as that in the second embodiment shown in FIG.
[0026]
